Dragino WSC2-C-GE, NB-IoT/LTE-M Transmitter for weather stations, without SIM card

The Dragino WSC2-C is the cellular version of the WSC2 weather station transmitter, featuring support for NB-IoT and LTE-M (CAT-M1). It reads connected weather sensors via RS485 and pulse input, transmitting measurement values directly to an IoT server over the mobile network without the need for a separate gateway. The choice between two cellular technologies allows the transmitter to be used even in locations where only one of the two is available.

Key Features:

• NB-IoT and LTE-M (CAT-M1) in a single device, no separate gateway required
• Data transmission via MQTT, MQTTS, TCP, UDP, or CoAP to your own servers or IoT platforms
• Supports all Dragino WSS weather sensors, third-party RS485 sensors, as well as optical or tipping bucket rain gauges at the pulse input
• Configuration via Bluetooth 5.1, AT commands, or downlink; firmware update via Bluetooth or wirelessly via OTA
• External 12V power supply with an integrated 1000 mAh Li-ion battery for buffering, IP66 enclosure for outdoor use

Specifications:

Interfaces, Configuration, Power Supply, Enclosure

• [identical to WSC2-N]

Scope of Delivery

• 1 × WSC2-C-GE transmitter (without SIM card, without sensors, without solar power supply)

Compatible Sensors:

• WSS-09, 9-in-1 weather sensor with ultrasonic wind measurement
• WSS-08, optical rain gauge
• WSS-21, tipping bucket rain gauge
• WSS-22, wind speed and wind direction sensor
• WSS-23, CO2 and fine dust sensor PM2.5/PM10
• WSS-24, rain and snow sensor with heating
• WSS-25, temperature, humidity, light, and air pressure sensor
• WSS-26, global radiation sensor
• WSS-27, PAR sensor

Commissioning note: The -GE version is supplied without a SIM card and without a pre-configured server. Before use, a nano-SIM capable of NB-IoT or LTE-M must be inserted, the APN set, and the target server configured via AT command. Network coverage at the site should be checked in advance.

Areas of Application:

• Agricultural weather stations in regions without LoRaWAN infrastructure, with the option to switch between NB-IoT and LTE-M depending on local coverage
• Cross-border or pan-European projects where different cellular technologies are available depending on the country
• Municipal climate and environmental monitoring networks with direct connection to existing MQTT or cloud platforms
• Individual, widely distributed measuring locations where deploying a dedicated LoRaWAN gateway per site is not cost-effective
